About This Book
The quiet rustle of pages mixes with the soft scuttle of tiny spider legs in a hidden corner of the Boston Library. Nestled among ancient books, the Deadlies spin delicate webs and keep watch over their secret home. But when a sneaky thief sneaks in, will their clever webs be enough to catch the culprit and save their cozy hideout?
Themes
Quick Assessment
The Deadlies, a family of friendly but misunderstood spiders, search for a permanent home and find a welcoming librarian in the Boston Library's Rare Books room. When a thief begins targeting the library, the spiders try to help catch the criminal in a lighthearted mystery. Parents should know the peril is mild and the spiders' toxicity is treated with humor, though the family's repeated displacement and feeling unwanted are recurring emotional threads.
